Aiming AdjustmentNKS003P5
PREPARATION BEFORE ADJUSTING
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on flat surface.
3. Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant, engine oil filled up to correct level and full fuel tank.
LOW BEAM AND HIGH BEAM
1. Turn headlamp low beam ON.
2. Use adjusting screws to perform aiming adjustment.

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to IPDM E/R across the CAN communication lines. The CPU located in the
IPDM E/R controls the headlamp low relay coil, which when energized, directs power
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 8,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 8.
Ground is supplied
to front combination lamp RH terminal 4
to front combination lamp LH terminal 4
through grounds E22 and E43.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation (When Daytime Light Does Not Operate)/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH BEAM or PASSING position, the BCM receives
input signal requesting headlamp high beams to illuminate. High beam request signal is communicated to the
IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls headlamp high
relay coil and low relay coil, which when energized, directs power
through 10A fuse (No. 72, located in IPDM E/R)
through IPDM E/R terminal 27
through front combination lamp RH terminals 6 and 2
to daytime light relay terminal 3,
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 6,
through 15A fuse (No. 76, located in IPDM E/R)
through IPDM E/R terminal 20
to front combination lamp RH terminal 8,
through 15A fuse (No. 86, located in IPDM E/R)
through IPDM E/R terminal 30
to front combination lamp LH terminal 8.
Ground is supplied
to daytime light relay terminal 4
to front combination lamp RH terminal 4
to front combination lamp LH terminal 2
to front combination lamp LH terminal 4
through grounds E22 and E43.
With the power and ground supplied, the headlamp high beam and low headlamp illuminate.
High beam indicator illuminates when combination meter receives input signal requesting high beam indicator
to illuminate. This is communicated to BCM across the CAN communication lines.

HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
Revision: 2006 January2006 M35/M45
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and
parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This
input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime
light relay coil. When energized, this relay directs power
through daytime light relay terminals 5 and 3
through front combination lamp RH terminal 2
through front combination lamp RH terminal 6
through IPDM E/R terminal 27
through 10A fuse (No. 72, located in IPDM E/R)
through 10A fuse (No. 74, located in IPDM E/R)
through IPDM E/R terminal 28
to front combination lamp LH terminal 6.
Ground is supplied
to combination lamp LH terminal 2
through grounds E22 and E43.
With power and grounds supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
